Active clinical trials for "Sleep Wake Disorders"

The purpose of this research study is to compare the effectiveness of Zolpidem CR to that of placebo in improving sleep efficiency in people with dementia admitted to the hospital because of their symptoms. You can participate in this study if you have dementia of the Alzheimer's type or vascular dementia. This study involves placebo; a placebo is a tablet that looks exactly like Zolpidem CR, the study drug, but contains no active study drug. We will use placebos to see if the study results are due to the study drug or due to other reasons. Zolpidem CR is also called Ambien CR and is widely available by prescription. Zolpidem CR is approved by the U.S. Food and Drug Administration (FDA) for the short-term treatment of insomnia (trouble falling or staying asleep).

The purpose of this study is to evaluate the efficacy and safety of a six month double-mask treatment of tasimelteon or placebo in male and female subjects with Non-24-Hour Sleep-Wake Disorder

The purpose of this study is to compare the effectiveness of two talk therapies for OEF/OIF Veterans at the Michael J. Crescenz and the West Haven VA Medical Centers. Participants will randomly receive one of two individual treatments intended to improve the sleep disturbance and nightmares of returning Veterans.

The primary objective of the study is to evaluate whether armodafinil at a target dosage of 200 mg/day is more effective than placebo treatment in improving excessive sleepiness in patients with obstructive sleep apnea/hypopnea syndrome (OSAHS) who have comorbid major depressive disorder or dysthymic disorder.

The purpose of this study is to evaluate the ability of ramelteon, once daily (QD), to advance the timing of sleep in individuals with delayed sleep phase syndrome.

The primary aim of the study is to test the effect of mindfulness training on sleep parameters among older adults with insomnia symptoms The secondary aims are to examine if changes in mindfulness meditation practice (daily log) and level of mindfulness (self-report) are associated with changes in sleep parameters, and to determine if mindfulness training is associated with in vitro biological markers of peripheral inflammation

The objective of this trial is to assess the effect of rotigotine (SPM 962) on the control of early morning motor impairment and sleep disorders in subjects with idiopathic PD. Subjects who meet eligibility criteria will begin treatment with rotigotine transdermal patches. Trial medication will be titrated to an optimal daily dose, or to the maximal dose. Following a Titration period of up to 8 weeks, subjects will be maintained on the optimal or maximal dose for 4 weeks. After the Maintenance period, subjects will have the option to enter into an open-label extension study. The first subject was enrolled in December 2004. The last subject was enrolled in April 2005 and the last subject visit was conducted in July 2005. This study is now closed

Sleep problems can lead to a bad quality of life and a raise of morbidity, also in dialysis patients. Sleep problems can be caused by a disturbance of circadian rhythms in our body. For a good regulation of these circadian rhythms a uniform external synchronisation is necessary. This is the synchronisation of the biological clock of our body by light and other influences. In case of a disturbance of the external synchronisation, due to for example naps during the day or wake periods at night, internal rhythms can be unlinked. As a result a weakened melatonin rhythm and a problematic sleep-wake cycle can be observed. Most dialysis patients have sleep problems. Their sleep latency is prolonged. They often take a nap during the day and their sleep efficiency is poor. There has only been one study on the melatonin rhythm of dialysis patients. The conclusion of this study was that the melatonin rhythm of dialysis patients is weakened and disturbed, probably caused by renal insufficiency. In this study no link was made between melatonin rhythm and the nature and severity of possible sleep problems. In different studies with non-dialysis patients and a disturbed melatonin rhythm, exogenous melatonin at the right time leads to a recovery of the normal rhythm and the normal biological clock and a better quality of life. The aim is to research the endogenous melatonin rhythm and to improve sleep problems of hemodialysis patients with a placebo-controlled study with exogenous melatonin. Next to this a substudy is performed, in which the effect of the change of daytime to nocturnal in hospital hemodialysis on sleep and melatonin is researched.

This study will compare the symptoms, experiences, and laboratory sleep characteristics of young adults with and without insomnia.

Smoking is a major health problem with a direct link to elevated heart- and lung-related problems. Nicotine is highly addictive, which makes quitting difficult and relapse after quitting highly probable. Any type of sleep disturbance may make quitting even harder. The purpose of this study is to evaluate the effect of bupropion and nicotine replacement therapies (NRT) on sleep disturbances. In turn, this might show how such medications affect attempts at smoking cessation.
